I tried to compile Demo3 from inside MPlab after changing the paths of the various source files and setting the include path to include the .h locations

Any attempt to build or make the project returns the message
BUILD FAILED - date&time
and no other message
I have checked and rechecked but can't find the fault

The original project returns the expected cant find... errors
can anyone offer any suggestions

> BUILD FAILED - date&time and no other message

Not very helpfull of it!

Is it just demo3 or the same for all? I think there is a difference in demo3 for the compiler path but I don't know why this would cause a problem.

I tried to compile the RTOS for the PIC18F6680 and then I got the error Messages
pastet below. I used the following script for the Linker.
Can anyone help me.

You need to combine all the small blocks of RAM into a block large enough for the kernel memory pool to fit into.

Take a look at the 18f452.lkr file in the demo/PIC directory to see how this can be done. Look for the BIG_BLOCK block within this file.

re original message
I found a line at the bottom of the .lnk file defining the compiler program path which I had missed
When I pointed that to my compiler All was fine
